Not just an encouragement but also a boost to the popularity of bitcoin overall because these move by Twitter is going to make more people adopt bitcoin because Twitter has legions of influencers that's going to do their thing and start sharing their thoughts on this thing and using their own influences.
one by one big companies started accepting bitcoin, and twitter is one of the biggest social media that currently accepts bitcoin. this will certainly make twitter users more familiar with bitcoin. this is a wonderful thing. I'm pretty sure little by little developments regarding bitcoin will be very widespread. although there are quite a lot of repeated FUDs, but I strongly believe developments like this will make bitcoin adoption more widespread. well, I'm waiting for the next big company to accept bitcoin. this is amazing.
